It doesn't take long to slip them back in. Especially if they're off the dog bones. The ones on the swingarm might take a touch longer. Seriously like 15mins work.
In saying that it looks to me like the washers only shield the seal itself from the elements. They aren't load bearing so you could probably get away without having them there for a ride if you're going to pull it and clean the grot away from the seal later anyway.
